获取查询Bigquery的直方图

Question

问题是：显示客户在2018年4月1日至10日之间完成的RIDE订单的交易分布（已完成1笔交易，2、3、4等的客户的分布）

并且正在查询的表的预览是：

我的查询是：

SELECT customer_no, COUNT(*) AS total_transaction FROM [bi-dwhdev-01:source.daily_order]
WHERE DATE(order_time) >=  '2018-04-01'AND DATE(order_time) <=  '2018-04-10'
GROUP BY customer_no
ORDER BY total_transaction DESC;

我想知道如何在Bigquery（旧版或标准版）中获得发行版？预先感谢！

Answer 1

我认为您需要两个聚合级别：

SELECT total_transaction, COUNT(*)
FROM (SELECT customer_no, COUNT(*) AS total_transaction
      FROM [bi-dwhdev-01:source.daily_order]
      WHERE DATE(order_time) >=  '2018-04-01' AND DATE(order_time) <=  '2018-04-10'
      GROUP BY customer_no
     ) c
GROUP BY total_transaction
ORDER BY total_transaction DESC;
